SWIVELING TRUMPET FOR TELEPHONES.

SPECIFICATION forming part of Letters Patent No. 715,878, dated December16, 1902.

Application filed April '7, 1902.

To all whmn it may concern:

Be .it known that I, ARTHUR SOHOELER, merchant, a subject of the King ofPrussia, German Emperor, residing at Elberfeld,in the Kingdom ofPrussia, German Empire,have invented new and useful Improvements inSwiveling Trumpets for Telephones, of which the following is aspecification.

My invention relates to a swiveling trumpet for telephones; and theimprovement consists in certain arrangements and combinations of parts,as are describedhereinafter and represented in the accompanyingdrawings, in which Figure 1 is a front view, and Fig. 2 a longitudinalsection view.

The advantage of this trumpet is that it may be adjusted on any heightfor the mouth.

The construction 'of the swiveling trumpet is as follows: The clamp a isturned on the inside and can be attached to the telephonecasing by meansof the four screws b. On the other side the clamp a is provided with arecess for receiving an annular spring 0 of a V-section. The trumpet dis provided with a flange e, which is placed on the spring 0 into thesaid recess of the clamp and held by a Serial No. 101,829. (No model.)

flange f. The latter fits loosely on the flange e andis secured on theclamp a by, say, four screws g. On screwing home these screws the flangef will press the flange 6 against the yielding spring 0, whereby thetrumpet will be secured in its position into which it has been turnedand will be prevented from turning downward, owing to its weight.

Having now described my invention, what I desire to secure by LettersPatent of the United States is- The combination with an annular clamphaving a plurality of set-screws for securing it to a telephone-casing,of a swiveling bent trumpet having a flange, an annular spring arrangedto bear against said clamp, and an annular disk secured to said clamp byadjustable screws for pressing said flange of said trumpet against saidspring so as to secure y friction said trumpet in any position,substantially as set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
